MEANS AND APPARATUS FOR UTILIZING WASTE HEAT FOR PRODUCING MOTIVE POWER.

SPECIFICATION forming part of Letters Patent No. 439,259, dated October 28, 1890.

Application filed August 14, 1888. Serial No. 282,720. (No model.) Patented in Belgium January 28, 1888,1To. 80,431 in France February 6, 1888,11'0. 188.572, and in BnglandMarch 26,1888,No. 4,637.

To all whom it may concern.-

Be it known that I, CHARLES TELLIEE, a citizen of the Republic of France, residing at Paris, France, have invented certain new and useful Improvements in the Means and Apparatus for Utilizing Waste Heat for Producing Motive Power, (for which I have obtained Letters Patent in Great Britain, No. 4,637, dated March 26, 1888; in France, No. 188,572, dated February 6, 1888, and in Belgium, No. 80,431, dated January 28, 1888,) of which the following is a specification.

In my application, Serial No. 226,245, tiled February 2, 1887, I described an apparatus for utilizing solar or atmospheric heat.v The apparatus which I am about to describe has for its object to produce motive power by utilizing the exhaust-steam from steam-engines.

This apparatus is represented in elevation, partly in section, in Figures 1, l, and 11j in the accompanying drawings.

A is a receiver, into which enters through a tube a the exhaustfsteam from a condensing or a free-exhaust steam-engine. This receiver is made of five or six times the capacity of the motor-cylinder, as it must be large enough to allow the exhaust to takeV place without meeting with abnormal resistance, which would weigh uselessly on the motorpiston and diminish its useful effect. The receiver A is directly connected to a chamber or condenser B, which contains a number of tubes opening at one end into the receiver A and at the other end into a collecting-chamber b. The exhaust steam can thus pass freely through the'said tubes into the chamber b. The condenser B is filled with an aqueous solution of ammonia up to the line b b. In passing through the tubes of the condenser B the steam in condensing heats the ammoniacal solution, while the water of condensation will run oft' through the tube c c', whence it can be conducted back by a feed-pump to the boiler of the works. In heating the ammoniacal solution contained in the condenser B the steam will have produced ammoniacal gas, which, disengaged from solution, will be stored in the upper part of the condenser B and in the vaporquired motive power.

G of the superheater F allows of conducting chamber C placed above it. The ammoniacal vapors thus disengaged carry along with them a certain quantity of this solution, which it is important to eliminate. For this purpose I place over the condenser B a vapor-chamber C, communicating with the condenser B by means of tubes d for the passage of the ammoniacal vapors, and by means of other tubes d and d2 for the return of the liquid portion to the bottom of the condenser B. Further, I interpose at the joint e e a sheet of very line wire-gauze,whic.h bursts the scum bubbles drawn along and allow the ammoniacal gas to escape in a pure condition through the tube E, while the liquid runs through the tube s into the tube e c.

Another arrangement consists in placing above the condenser C a steam-chest E', containing asort of funnel of wire-gauze e e, allowing of the separation of the gas from the scum. The vapors thus produced is of sufficient pressure to be sent into the motorcylinder. As, however, it has been produced at a temperature of from 50 to 60 centgrade, it can be superheated to 150 or more. For this purpose I cause it to pass through the tubes of a superheater F, around which I cause steam from the boiler of the works to circulate. The steam enters the interchangerF through the tube f, and the water of condensation therefrom passes off through the tube f, whence it passes to the boiler either directly, if under equal pressure, or by means of a special pump. A v The ammoniacal vapor passes out from the vapor-chamber C through the tube g g to the base G of the superheater F, rises through its tubes, becomes superheated, and is conducted into the chamber G', placed above the superheater. Thence througha tube g it passes to a motor H, of any suitable known construction, which it actuates, thus producing the re- A tube g at the base back into the return-pipe e c any liquid which might be' drawn into the superheater. A tube g 9 conducts the ammoniacal vapor which has been employed in the motorcylinder into an absorption-chamber I, which is made in two parts, one of which is avapor- IOO , a cold state.

K a current of weak ammoniacal solution drawn from the lower part of the condenser B through a tube k. As this solution is hot and it is necessary for it to arrive in as cold a state as possible in the absorbing-chamber K,I first cause it to pass through the interchangers M Aand N, which will be hereinafter described, and then through the regulatingchamber o, which bringsv it in a cool state through the tube Z into the base of the absorbing-chamber K. In this chamber K the level of the liquid is maintained up to the line Z l by means of a float L.

The ammoniacal vapors contained in the chamber J pass into contact with the cold solution of the chamber K by means ot holes P PPP. These holes through tubes p p p p, lead- 1ng to horizontal tubes p p p p', which are perforated, allow the ammoniacal gas to become dissolved in the cold solution contained in the chamber K; but in order to remove the heat'produced by the condensation of the amlnonlacal vapors and by their combination I arrange inside the absorbing-chamber K a large number of tubes arranged in clusters or sets, as shown in the caps Q Q Q, which allow cold water arriving through a tube q to travel over the clusters of tubes, Which water then leaves by the tube q, having taken up all the caloric. The amm oniacal solution, being thus re-formed, is sent back by means of .the pump R into the condenser B to render the operation continuous. As the solution is cold while there is a temperature in the condenser of from 50 to 60, it is advisable to heat the solution. Now a hot solution is constantly leaving the condenser and passing into the absorbing-chamber K and is required to enter in It is advisable therefore to eiect an exchange of the heat. For this purpose I conduct the hot sol ution leaving the condenser through the tube 7c k 7c k to the upper part m of the interchan ger M. It descends through the tubes of the interchanger to the base m thereof. Thence it leaves through a tube m.

' On the other hand, the cold liquid coming from the absorber K through the tube t is sent by the pump R through the tube into the lower part of theinterchanger M, in which it rises to the top at In rising it becomes heated by contact with the hot liquid coming from the condenser B, so that it leaves in a heated state through the tube e e e e', and is returned to the lower part of the condenser B, while the weak hot solution coming from the condenser B through the tube k enters at min a hot condition. As its temperature is not yet low enough to allow of its being sent direct into the absorber K, I cause cold condition, whence it is conducted to the absorber K. As the liquid to be cooled enters the interchangers at the top, it is important, in order that the surfaces shall act efficiently, to keep the interchanger-tubes full of liquid. For this purpose I employ an overflow-chamber O, serving to maintain the level of the liquid iu the iuterchangers at the proper height. p

From this description it will be understood that the absorber K receives weak liquid at a very low temperature, while the condenser B receives the hot and strong ammoniacal solution. Above the chamber o, in which the iioat L is placed, serving to maintain the level in the absorber K, is a tube 'w w, surmounted bya short tube S and a tube s. The tube w w serves to establish the equilibrium between the tloatL and the absorber K. The tube s leads either to an air-pump and a purier ot' suitable construction (not shown in the drawings) or to a blow-oft. This arrangement serves to extract the air which may have entered the apparatus andv to insure its proper working. The purifier, which may be worked with plain or acidulated water, is for the purpose of collecting the ammoniacal vapors.

The air which may be drawn iuto the condenser B by the steam is removed by means of a second air-pump communicating with the tube z.

Another interchanger is shown detached at Z. It is placed there with the object of showing that the vapors passing out of the motor H can be caused to pass through its tubes, and that on the other hand by causing the ammoniacal vapors going to the superheater F to pass around its tubes a portion of the sensible caloric brought by the ammoniacal vapors coming from the motor H can thus be recovered for superheating the said vapors.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is- In apparatus for producing motive power through the medium of an aqueous solution of ammonia, the combination of the vaporizing-condenser B, provided with the separator hereinbefore described, the superheater F, the absorbing-condenser K, and the temperature-exchangers M aud N with a motor H.
